FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. 394,526, dated December 11, 1888.

Application filed July 23, 1888. Serial No. 280,786. (No model.)

To all whom it may concern.-

Be it known that we, HENRY VOGT and ROBERT II, BURNs, citizens of the United States, residing in Brooklyn, Kings county, and State of New York, have invented certain new and useful Improvements in Feed- Water Heaters, of which the following is a specification, reference being had to the accompan yin g drawin Our invention relates specially to improvements in feed-water heaters, and has for its object the cleansing of the feed-water while passing through the heater, as well as the cleansing of the exhaust-steam of the grease carried with it from the engine.

The improvements consist in the construction, arrangement, and combination of the sev eral parts or portions comprising the heater, as hereinafter described and specified.

In the drawings, Figure 1 represents a vertical section through a heater embodying my improvements. Fig. 2 represents a plan View of the grease-extraeting portion of such heater. Fig. 3 represents a section of the grease-extracting chamber,with detailed view of greasecollecting wheel.

Similar letters of reference designate like of the chamber or drops to the gutter m. and

parts or portions in all the figures.

The letter A designates the main inclosingchamber of the heater.

B designates a series of outer tubes, and C a series of inner tubes, forming an annular space or passage between the two, through which the feed water moves while being heated.

D designates the upper and E the lower water-chamber of the heater, joined by the annular spaces between tubes B and C. F, the feed-water inlet, is bent to provide for the expansion and contraction of the heater-tubes.

G designates apipe or duct providing direct communication between water-chamber E and a bottom chamber, H.

I designates a receiving-chamber for exhaust-steam, from which the steam passes up through the tubes 0.

J designates a grease-collecting wheel,which is caused to revolve by the movement of the steam as it enters the receiving-chamber. The wheel J is fitted with a hub, K, revolving upon the connecting-pipe G.

M is the exhaust-inlet, preferably set at a tangent to the circle of the receiving-chamber to guide the entering steam directly against the face of the wheclblades.

N is the exhaust-outlet.

is the feed-water outlet leading to the boiler.

The chamber I is preferably formed with a conical bottom to provide drainage for the grease as it collects. The circular portion in forms a gutter, from which it is blown out through blow-pipe II.

a and a are blow-oft nozzles for cleansing chambers A and E of any settlement.

In the operation of the heater, steam enters the receiving chamber I, and, impii'iging against the blades of wheel J, causes it to revolve, and while in contact with the blades it leaves the grease adhering to the metal. By the revolution of the wheel J greater and more e'ltective contact is brought about be.- tWeen the wheel faces and the steam, resulting in a thorough cleansing of the steam of all grease before it enters the tubes C; also, the grease is caused by centrifugal force to move toward the periphery of the wheel J, whence it is thrown against the vertical walls is blown out through pipe at. In the heater, as shown, the steam passes from the chamber I to and through the tubes to the upper portion of the main chamber A, thence down about the larger tubes, 1-3, to the outlet-nozzle N. The water of condensation is blown out through pipe 11 The feed-water to be heated enters the chamber D through pipe F, and passes down through the annular spaces between pipes B and C to lower chamber, E, whence it passes through pipe G to the bottom chamber, II, where, the water being quiet, the materials of heavier gravity settle to the bottom and are blown out at 72 Any style of heater maybe used in connection with the two cleansing-chambers, it being only necessary that the steam for heating shall enter chamber I and the feed-water shall be discharged through settling-chamber H. \Vhere the water is clean, chamber H may be omitted and the feed discharged from chamber E direct, pipe G taking the place of boiler-connection O.

with the main inclosing-chamber A, tubes 0 a and B, connected chambersD and E, pipe G, exhaust-receiving chamber I, grease-collector J, and settling-chamber II, substantially as and for purposes specified.

4. In a feed-Water heater, the combination of the tubes B and C, chambers D and E, connected by said tubes B and C, exhaustreceiving chamber I, grease-collector .T, and discharge-tube G, substantially as and for purposes set forth.
